Water with a sulphate concentration of 70 mg/L is discharged into a river at a flowrate of 700 m³/d. The flowrate of the river is 18000 m³/d and the SO4²- concentration is 30 mg/L before the discharge. What is the total flowrate at the end of the mixing zone? m³/d i) Qtot = ii) [SO4²] = What is the concentration at the end of the mixing zone? mg/L
